i To 60% whom it may concern.-

Referring to the accompanying drawings,-

Figure 1 is a vertical longitudinal section of the machine. Fig. 2 is a vertical cross-section thereof. Fig. 3 is a bottom plan view with parts removed. Fig. 4 is a perspective view of the front end of the machine, with parts removed. Fig. 5 is a detail view of a portion of the stuffing box, showing the means 1 for equalizing the adjustment of the plates.

Fig. 6 is a perspective view of the machine, with cover raised. Fig. 7 is a front end view of the machine, with cover closed and gate lowered. Fig. 8 is a perspective view of the gate detached. Fig. 9 is a vertical cross-section of the gate; and Fig. 10 is a detail side view of the front end of the machine in vertical section. i

A, indicates the frame of the machine constructed with four corner posts a, connected to and braced by horizontal beams to.

The floor, sides, spout, gate and cover of this machine are constructed and arranged as hereinafter set forth, so as to be simultaneously or synchronously adjusted by one operation. The stuffing box is constructed with side-rails B, B, to which are permanently attached horizontal side-boards I), each side-rail and side-board being united by a metallic brace C, which is bent at its lower end, as shown, to embrace a not a mounted on a transverse shaft F arranged beneath the stud-- ing box and provided with a right and left hand screw thread. Said shaft passes through the brackets G, as shown. The floor of the stuffing box is formed, in connection with the side-boards b, of longitudinal rails D, D, D and D arranged at equi-distances apart, and metallic sheets or plates E, E, the sheets E screw threads on said shaft F.

is provided with a sprocket wheel f. The

sprocket wheels fare connected by a sprocket chain f, whereby the, shaft F will be operated by the rotation of the shaft F. The shaft F is mounted in brackets depending from the Sideboards b, and similar to the brackets C, and is provided with nuts similar to the nuts 0, engaging right and left hand By means of this mechanism the ends of the bottom of the stuffing 'box will be moved simultaneously. A crank being applied to the shaft F, the sideboards, rails and plates of the bottom may be simultaneously adjusted laterally.

, G indicates the cover of the stuffing box which is constructed with longitudinal rails 1, 2, 3, 4:, 5, 6,7, plates 8, 9, 10, and horizontal side-boards g, g, connected-and arranged together similarly to the floor of the stuffing box. The side-boards g,g, are provided with depending hook-shaped brackets, H, H adapted to overlap and engage the side-rails B,'B, when the cover is closed and thereby cause the cover to be laterally adjusted simultaneously with the bottom and sides of the stulf ing box by a single operation of the crank on the end of shaft F.

The cover G is connected at its rear to a,

rotary rod I by a hinged connection laterally adjustable on said rod as the cover is laterally adjusted. The ends of the rod I rest in bearing blocks 7', which are adjusted vertically in uprights by means of screw-threaded vertical shafts K engaging nuts 7o located in recesses in said blocks j, each of said shafts K being provided with beveled gears k k connected to corresponding gears K? on a transverse shaft 10 operated by a suitable crank. By means of the foregoing mechanism the rear end of the cover G may be vertically adjusted to stuif mattresses of different thicknesses.

In order that the rails and plates of the otedto :one of the corner posts 0.

bottom and cover of the stuffing box may be caused to maintain equal distances apart in their lateral adjustment, an equalizing adjusting mechanism is provided, preferably consisting of lazy-tongs d, which are connected at their ends to the side-boards of the bottom and cover, and to such of the rails as are adjusted laterally, as hereinbefore set forth.

The cover G is braced and strengthened by truss rods L, which are secured to the ends -of the cover and pass over a central bridge Z, l

zontal metallic sheetM, M having its inner 1 dg lapping the plate M and .its outer edge turned up to form a flange M which .is fastenedto the projecting end of each side rail B. The aforesaid construction forms the lower;

half of the spent.

The upper half thereof is I formedlbythefront end of the cover G being extendedso as to extend out over to the outer edgesiof the plates M,hl, 1W, when the cover Q isllowered. The outerendsof the side-boards g, ,g, of the vcover are also provided with depending .fla-nges G, whichoverlap the flanges M and form therewith thesides of the spout.

1R indicates thegateagainstwhich the stulf is compressed Eby the plunger. The gate R is movable vertically in a passage way R between the spont and the floor .of thestufing box and in .the side-rails B,.as shown in Figs. 4 and 10. The gate R, as moreclearly shown inIEig. 8, consists of a central plate 'Y and sideplates Y, Yfioverlapping the plate Yq The central plate Y is fixed .in a trough or lilashaped bar y and the side-plates Y, 1?, have their lower edges resting in said bar 3 and are adapted to slide laterally therein over .the ,plat-eJY. Theplates'Y, Y3, areconnee'ted to the side-rails B by flanges 1 g which engage T-shaped slots R in the siderails '33 and which permit of a vertical move-;'

ment of the plates Y, Y Thegateis raised and lowered by a suitable mechanism, such as "the metallic frame Z, which is secured to the central plate Yand the vbar andahand lever Z" extending transversely .to the front end of the machine below the spout and pivmay be .normally held up by .a bell-crank leverTZ anda spring Ztmounted on thefr'ame of the machine and connected to the hand lever Z. 'If desired, removable gates ofdif-- ferent sizes maybe employed, in lionof an adjustable gate.

It will be readilylnnderstood from the fore going description that with the connections of the gate and spout with the side-rails B, B, the bottom, sides, cover, and spout maybe The gate adjusted laterally by one operation of the shaft F.

N indicates the plunger, provided upon its under side with a screw-threaded shaft D, extending lengthwise beneath the stnfiing box, said shaft having loosely arranged on its rear end two oppositely driven pulleys P, P, and having keyed thereon a longitudinally adjustable clutch Q, adapted to be shifted to engage either of said pulleys to rotate said shaft in either direction and thereby cause the plunger to stnlf mattresses of difit'erent sizes, its head is removable and heads of varioussizes may be employed; and the heads may also be made laterally adjustable, as shown at n in Fig. 6. .A space is provided between the bottom plates in order that the feed nut may have an unobstructed the entire length of the machine and that there may be no impediment to the advance of the plunger through the stuffing box.

To clamp the cover tightly =upon .thestnfiring material, the following described mechanism is employed: The front end ofthe cover is provided with a cross-bars, having at its U are pivoted the lower ends of vcrticaklnode V, screw-threaded at their upper ends and provided with binding nuts W. When .itis desired to clamp the cover, the rods V are moved into the slots of the plates 8 and the nuts W screwed down upon the latter. The cover .is then drawn down and held upon the .stufiing material in the box by'a lever X on the shaft T, the two positionsiof the lover X-bei-ng shown in dot-ted and full lines in Fig. 10.

, Theoperationof the machine will be readily understood from the foregoing description.

Amattress of a given widthand thickncssheing required to be stuffed, the .stnfing box, spout, gate and cover 'areJadj usted $0 the m essary width. The cover is then upon the stuffing material in the boxmd'the stuffing material pressed by the plunger. The ticking having been secured totheiepont in any suitablemanner to receivethestnfling material, thegateislowered, and lthepllnnger being moved forward, thestnfling material is forced into the ticking. By means of a machine constructedas herein set forth, the mschine may be quickly and readily adjusted at one operation .to stulfmattressesof difiGb ent sizes.
